voltage-frequency

[j.alberto]

Hi all,

I am trying to build a spice model to become voltage-frequency but I’m having a lot of troubles by using real components.

Does anyone a virtual component in Multisim able to become voltage-frequency or any other way that I can control the frequency of the clock source?

Thank you very much

Have you tried the Voltage-Controlled Square-Wave source?

Yes Nestor,

I have tried the Voltage-Controlled Square-Wave source, it’s the perfect component for my purpose but its main limitation is the capability to change the duty cycle by external components.

Do you know any way to vary the duty cycle by external components or by spice syntaxes? The model that I’m making will be inside an integrated circuit that’s why I need to program the frequency and duty cycle by using external components.

I appreciate your help Nestor,

Not that I know of... for that purpose I would suggest the answer user Lacy gave to you in the other posting:

That looks easier...
